Q: Why high cylinders will read as there off axis when they are not?

A: One reason could there be maybe a lot of pressure about the lens, especially with your wire frames, loosen the screw several turns and take another look, if the lens now reads on axis, take just a little off the size of the lens with a hand stone.

Other reason will be the lens is just not being placed in a suitable position with your focimeter, any high cylinder(3 and above) are responsive to the angle the lens is sitting at due to the pressure in the lens stop. you can usually notice this by moving the lens table vertical. in the event you go through the lens on the side in the focimeter, you can often note that it can be sitting with an angle as much as 20 degrees. you should look at the lens within the focimeter while its on the same angle as worn through the patient.
